Abstract：Objective To evaluate the clinical outcomes of posterior unilateral open-door laminoplasty and Centerpiece titanium plate internal fixation in the treatment of multi-segmental spinal stenosis combined with cervical spondylotic myelopathy ( CSM ), and to provide a reference for the surgical treatment of cervical spondylosis. Methods From March 2011 to May 2014, 42 patients with multi-segmental spinal stenosis combined with CSM were treated by posterior unilateral open-door laminoplasty and Centerpiece titanium plate internal fixation. There were 24 males and 18 females, whose mean age was ( 62.5±6.8 ) years old ( range: 52-74 years ). The preoperative and postoperative Japanese Orthopedic Association ( JOA ) and Visual Analogue Scale ( VAS ) scores were analyzed, and the changes in the cervical curvature and cervical range of motion ( ROM ) were recorded.Results The JOA scores preoperatively and at 2 weeks and 3 months after the operation were ( 7.11±1.58 ) points, ( 13.42±1.25 ) points and ( 13.89±1.50 ) points respectively, and there were statistically signiifcant differences between the preoperative and postoperative scores (P<0.05 ). The VAS scores preoperatively and at 2 weeks and 3 months after the operation were ( 4.03±1.72 ) points, ( 1.47±1.69 ) points and ( 1.35±0.92 ) points respectively, and there were statistically signiifcant differences between the preoperative and postoperative scores (P<0.05 ). The cervical curvature angles preoperatively and at 3 months after the operation were ( 28.13±4.51 ) ° and ( 26.19±6.64 ) ° respectively. The cervical ROM preoperatively and at 3 months after the operation were ( 39.52±9.98 ) ° and ( 35.45±13.22 ) ° respectively, and no statistically signiifcant differences existed between them (P>0.05 ).Conclusions The clinical outcomes of posterior unilateral open-door laminoplasty and Centerpiece titanium plate internal ifxation are satisfactory in the treatment of multi-segmental spinal stenosis combined with CSM, with the advantages of relieving the neck and shoulder pain, alleviating the neurological symptoms, preserving the cervical curvature and ROM and improving the quality of life of the patients.
